Dear Foamers,

I am trying to run an edited pisoFoam solver for LES- Simulation.
Herby the Fourier Law approach for the heat flux is replaced by an other approach.
The quality of the mesh is OK (good). I could start simulation using the same mesh with other solvers.
I am using cyclic patches but I am not running the case parallel.

I am not able to run to solver. After typing the solver command, I am getting this output:
Code:
Create time

Create mesh for time = 0

I am not able to understand the meaning of these errors:

Code:
#0  Foam::error::printStack(Foam::Ostream&) at ??:?
#1  Foam::sigSegv::sigHandler(int) at ??:?
As you can see there is no clear information concerning the error.

I was wondering, if someone can recognize the reason of this error.


I appreciate any help

Thanks in advance
